Wheel tire wear annually takes hundreds of thousands of rubber tons. In this regard, the issue of reducing this negative phenomenon is urgent, for which it is necessary to know what and how affects tire wear. Factors affecting the wear of elastic wheels can be different: recipe of the rubber compound, the amount of traction (or braking) force in contact with the road, the type of movement is straight or cornering, the installation angles of the wheels (camber and toe-in angles), tire design, driving mode - uniform or with acceleration (braking). In this paper, we consider the influence on tire wear of such parameters as the value of the longitudinal force acting in the contact, the camber and toe-in angles, the radius of the motion trajectory and such a structural parameter as the convexity of the tread. When assessing the wear intensity, as is accepted by most researchers, we proceed from the fact that wear is proportional to the friction power in the contact of two interacting bodies.
